CVE-2026-7130 Overview
A SQL injection vulnerability has been discovered in SourceCodester Pharmacy Sales and Inventory System version 1.0. The vulnerability exists in the /ajax.php?action=delete_category endpoint, where improper handling of the ID parameter allows attackers to execute arbitrary SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to access sensitive pharmacy and inventory data, modify database records, or potentially compromise the entire database server through the unvalidated ID parameter.

Technical Details for CVE-2026-7130
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Injection) occurs in the category deletion functionality of the Pharmacy Sales and Inventory System. The vulnerable endpoint /ajax.php?action=delete_category accepts an ID parameter that is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to inject malicious SQL statements that the database server will execute with the application's privileges.
The vulnerability is remotely exploitable without authentication, making it particularly dangerous for internet-facing deployments. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Due to the nature of pharmacy systems, successful exploitation could expose sensitive patient information, prescription data, and inventory records.
Root Cause
The root cause of this vulnerability is insufficient input validation and the lack of prepared statements or parameterized queries when processing the ID parameter in the delete_category action. The application fails to sanitize user-supplied input before incorporating it into SQL queries, allowing special characters and SQL syntax to be interpreted as database commands rather than data.
Attack Vector
The attack vector is network-based, allowing remote exploitation without requiring authentication. An attacker can craft malicious HTTP requests to the /ajax.php endpoint with a manipulated ID parameter containing SQL injection payloads. The lack of input validation means the attacker's SQL code is executed directly by the database server.
By manipulating the ID parameter in requests to /ajax.php?action=delete_category, an attacker can inject SQL commands such as UNION-based queries for data extraction, time-based blind injection for enumerating database contents, or stacked queries for data modification. Technical details are available in the GitHub Issue #11 Discussion and VulDB Vulnerability #359729.
Detection Methods for CVE-2026-7130
Indicators of Compromise
- Unusual or malformed requests to /ajax.php?action=delete_category containing SQL syntax characters such as single quotes, UNION statements, or comment sequences
- Database error messages in application logs indicating SQL syntax errors from user input
- Unexpected database query patterns or slow queries indicative of time-based blind SQL injection attempts
- Unauthorized data access or modifications in pharmacy inventory or category tables
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP request parameters
- Configure database activity monitoring to alert on suspicious query patterns, especially those involving UNION, SELECT, or comment characters
- Deploy intrusion detection signatures targeting SQL injection attempts against PHP applications
- Enable detailed logging for the /ajax.php endpoint and monitor for anomalous ID parameter values
Monitoring Recommendations
- Review web server access logs for requests to /ajax.php?action=delete_category with unusually long or suspicious ID parameter values
- Monitor database logs for query errors or unusual data access patterns
- Set up alerts for multiple failed or malformed requests to the affected endpoint from a single source IP
How to Mitigate CVE-2026-7130
Immediate Actions Required
- Remove or disable the affected Pharmacy Sales and Inventory System from production until patched
- Block public access to the /ajax.php endpoint using web server configuration or firewall rules
- Implement web application firewall (WAF) rules to filter SQL injection attempts targeting the ID parameter
- Audit database logs for signs of prior exploitation or unauthorized data access
Patch Information
As of the last NVD update on 2026-04-29, no official patch from SourceCodester has been documented for this vulnerability. Organizations should monitor the SourceCodester website and vulnerability databases for patch availability. Given the publicly disclosed nature of this exploit, immediate compensating controls are critical.
Workarounds
- Implement input validation on the ID parameter to accept only integer values before processing
- Use prepared statements or parameterized queries in all database interactions
- Deploy a web application firewall configured to block SQL injection attack patterns
- Restrict access to the administrative interface and /ajax.php endpoint to trusted IP addresses only
- Consider replacing the vulnerable system with a more secure pharmacy management solution
Administrators should apply input validation at the application level. For Apache deployments, access can be restricted using .htaccess:
# Restrict access to ajax.php endpoint
<Files "ajax.php">
Require ip 192.168.1.0/24
Require ip 10.0.0.0/8
</Files>
